Description

This lesson demonstrates why and how grain orientation is an
important element in project design and product planning.  It
also demonstrates the relationship between grain orientation and
glue strength.



The lesson consists of lecture and several student
activities.  Each student will need several samples of scrap
stock with different grain orientations.  For lesson
preparation details, please refer to "prerequisites" within this
lesson plan.  You may wish to have the students glue up extra
stock samples for a broader range of testing.



If you use the "glue and grain strength" activities, this
lesson will cover more than one class session.
